Abstract

Official abstract text for this publication.

Provided is an organic electroluminescent lighting device which can be seen that the entire surface is uniformly illuminated from the side of a transparent electrode substrate even when an auxiliary electrode or an auxiliary wiring is provided with respect to the transparent electrode substrate. In an organic electroluminescent lighting device including a pair of electrode layers including a translucent electrode layer provided on a translucent substrate, at least one organic layer interposed between the pair of electrode layers and including a light-emitting layer, and an auxiliary electrode provided on the translucent electrode layer such that the auxiliary electrode comes in contact with a portion of the translucent electrode layer, the auxiliary electrode includes conductive metal particles having a particle diameter of 0.1 to 2 μm, and is covered with an interlayer insulating coating film for suppressing the conduction with the organic layer.

First claim

Opening claim text (preview).

What is claimed is: 1 . An organic electroluminescent lighting device comprising: a pair of electrode layers including a translucent electrode layer provided on a translucent substrate; at least one organic layer interposed between the pair of electrode layers and including a light-emitting layer; and an auxiliary electrode provided on the translucent electrode layer such that the auxiliary electrode comes in contact with a portion of the translucent electrode layer, wherein the auxiliary electrode includes conductive metal particles having a particle diameter of 0.1 to 2 μm, and is covered with an interlayer insulating coating film for suppressing the conduction with the organic layer. 2 . The organic electroluminescent lighting device according to claim 1 , wherein the conductive metal particles are composed of any of gold, silver, copper, aluminum, nickel, and alloys thereof. 3 . The organic electroluminescent lighting device according to claim 1 , wherein the interlayer insulating coating film contains a polymer and transparent insulating particles having a particle diameter of 0.1 to 2 μm which have a different refractive index from the polymer. 4 . The organic electroluminescent lighting device according to claim 2 , wherein the interlayer insulating coating film contains a polymer and transparent insulating particles having a particle diameter of 0.1 to 2 μm which have a different refractive index from the polymer. 5 . The organic electroluminescent lighting device according to claim 3 , wherein the transparent insulating particles are composed of any of titanium oxide, silicon oxide, and barium sulfate. 6 . The organic electroluminescent lighting device according to claim 4 , wherein the transparent insulating particles are composed of any of titanium oxide, silicon oxide, and barium sulfate. 7 . The organic electroluminescent lighting device according to claim 1 , wherein the auxiliary electrode and the interlayer insulating coating film are formed by screen printing, gravure offset printing, or ink-jet printing. 8 . The organic electroluminescent lighting device according to claim 1 , wherein a line width of the auxiliary electrode is 1 to 200 μm. 9 . The organic electroluminescent lighting device according to claim 1 , wherein a film thickness of the auxiliary electrode is 0.1 to 10 μm.
